Diagnostic Fault Information
Circuit/System Description
The steering wheel angle sensor receives a 12 V reference voltage from the electronic brake control module. The electronic brake control module receives serial data inputs from the steering wheel angle sensor identifying the position and direction of the steering wheel rotation. The module utilizes this signal to calculate the driver intended driving direction.
Conditions for Running the DTC
Ignition ON.
Conditions for Setting the DTC
C0710 00
The control module received an invalid steering angle sensor signal.
C0710 42
The steering wheel angle sensor is not calibrated.
C0710 5A
* No steering angle signal
* The steering angle signal is not plausible with the yaw rate sensor signal.
* The steering wheel angle sensor offset is out of specified range.
Action Taken When the DTC Sets
* The traction control/stability control-active indicator turns ON.
* The electronic brake control module disables the stability control and hill start assist for the duration of the ignition cycle.
Conditions for Clearing the DTC
* The DTC clears when the diagnostic runs and passes.
* The history DTC will clear after 40 consecutive fault-free ignition cycles have occurred.
Diagnostic Aids
* Improperly mounted or loose steering wheel angle sensor.
* The car should not pull in either direction causing the steering wheel to be off center while driving in a straight line on a level surface.
* Confirm that all tires are of the proper size and that all are matching brands. Check and adjust all tires to the stated cold air pressure as identified on the tire placard. If a miss sized or non-matching brand tire is present, inform the customer that in order for the vehicle stability enhanced system to function normally, tires need to be a uniform size and rolling diameter.

Circuit/System Verification
1. Ignition ON.
2. Verify the scan tool Steering Column Position parameter corresponds to the actual steering position as the steering wheel is turned through its entire range of motion.
• If the parameter does not correspond with the steering wheel position or the reading is erratic
Refer to Circuit/System Testing.
• If the parameter reading corresponds with the steering wheel position
3. All OK.
Circuit/System Testing
1. Ignition ON.
2. Verify that DTC U0073, U0074, U0125 or U0126 is not set.
• If any of the DTCs are set
Refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle.
• If none of the DTCs are set
3. Verify that DTC C0710 42 or C0710 5A is not set.
• If DTC C0710 42 or C0710 5A is set
Perform the Steering Angle Sensor Centering Procedures
• If DTC C0710 42 or C0710 5A is not set
4. Verify the B99 steering wheel angle sensor is installed correctly.
• If loose or incorrect installation
Correct the installation or replace the component.
• If correct installation
5. Ignition OFF and all vehicle systems OFF, disconnect the harness connector at the B99 steering wheel angle sensor. It may take up to 2 minutes for all vehicle systems to power down.
6. Test for less than 10 ohms between the ground circuit terminal 6 and ground.
• If 10 ohms or greater
1. Ignition OFF.
2. Test for less than 2 ohms in the ground circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, repair the open/high resistance in the ground connection.
• If less than 10 ohms
7. Ignition ON.
8. Verify a test lamp illuminates between the 12 V reference circuit terminal 5 and ground.
• If the test lamp does not illuminate
1. Ignition OFF, disconnect the harness connector at the K17 electronic brake control module.
2. Test for infinite resistance between the 12 V reference circuit and ground.
• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance
3. Test for less than 2 ohms in the 12 V reference circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, replace the K17 electronic brake control module.
• If the test lamp illuminates
9. Replace the B99 steering wheel angle sensor.
10. Ignition ON.
11. Verify that DTC C0710 does not set.
• If DTC C0710 sets
Replace the K17 electronic brake control module.
• If DTC C0710 does not set
12. All OK.
